Anyone have problems with algae in their outside storage tank?
I have a white, plastic IBC tank in a mostly-shaded part of my back garden in which I store my RO'd water. I notice a greenish band, about 4" high along one side of the inside of the tank where the surface of the water was about 3 days ago. (I have since transferred out most of the water to my van.)
Because I work part-time, I often have the water standing still for a few days.
It can't be anything other than algae, can it? I have 2 issues now:
1. I think I have to eradicate the little critters.
2. I need to stop them coming back.
Any advice, folks?
